Tesamorelin
What is common, what is less so, and what to do if something is out of the ordinary.
What most people notice
Mostly an injection-site reaction: redness, itching or slight tenderness, which clear on their own.
Joint or muscle aches, and slight swelling of the hands or ankles, are also common, especially in the first weeks.
What can also happen
- Tingling or slight numbness in the hands.
- Aches in the arms or legs.
- Itching or a skin rash, away from the injection site.
- Slightly higher blood sugar, especially at the start.
To reduce these effects
- Inject into the belly, as in the studies, changing the spot each time.
- Do not raise the dose on your own.
- If you live with diabetes or prediabetes, monitor your blood sugar more closely.
When to talk to a professional
With this product, especially if you notice:
- Tingling or numbness in the hands that lasts or gets worse.
- Marked swelling of the hands, feet or ankles.
- Intense thirst or unusually heavy urination.
- A reaction at the injection site that spreads or does not ease.
If a symptom is severe, lingers or worries you, stop the product and talk to a healthcare professional. An immediate reaction after the injection, such as trouble breathing or swelling of the face, needs medical care right away.
Specific to this product
- This product raises IGF-1, a hormone measured by blood test: before a blood test, mention it, as it can influence the result for several days.
- It is not recommended with an active or recent cancer, uncontrolled diabetes, a known disorder of the pituitary (a gland at the base of the brain), and during pregnancy and breastfeeding.
- If you take cortisone on an ongoing basis, or a medication whose dose must stay very precise, talk to your doctor first: growth hormone can change its effect.
- It should not be combined with growth hormone, or with another product from the same family: the effects would add up.
Anti-doping: Prohibited by the World Anti-Doping Agency (GHRH and its analogues, tesamorelin named explicitly, S2).
Where the research stands
Level of evidence: Documented in humans
How well it is tolerated is documented in humans by clinical trials lasting several months, conducted mainly in adults living with HIV. For other profiles, the data is more limited.
